The crankcase gas ventilation system is responsible for routing excess gases from the engine’s crankcase back into the intake system for reburning. However, in real-world truck operation — especially with high mileage and heavy loads — this system can start to malfunction. This often leads to oil entering the intake, reducing engine power, increasing fuel consumption, and causing premature contamination of the turbocharger and EGR system.

Using TruckTools software, we offer safe and professional crankcase ventilation disablement by adjusting the engine’s electronic control settings. The procedure is carried out remotely, with no physical intervention needed. Our experts connect online, perform diagnostics, and apply precise software adjustments.
Alternatively, you can purchase a TruckTools license to disable the crankcase ventilation system independently whenever needed.

Disabling this system protects the engine from contamination, improves performance stability, and extends the service life of critical components. It is particularly beneficial for trucks operating under heavy loads or with high mileage (over 500,000 km).
